Features - 20.11.0

v20.10.0 (2021-11-01)

Features - 20.10.0

  • If a "venv" install scheme exists in sysconfig, virtualenv now uses it to create new virtual environments. This allows Python distributors, such as Fedora, to patch/replace the default install scheme without affecting the paths in new virtual environments. A similar technique was proposed to Python, for the venv module - by hroncok (#2208)
  • The activated virtualenv prompt is now always wrapped in parentheses. This affects venvs created with the --prompt attribute, and matches virtualenv's behaviour on par with venv. (#2224)

Bugfixes - 20.10.0

  • Allow unfunctioning of pydoc to fail freely so that virtualenvs can be activated under Zsh with set -e (since otherwise unset -f and unfunction exit with 1 if the function does not exist in Zsh) - by :user:`d125q`. (#2049)
  • Drop cached python information if the system executable is no longer present (for example when the executable is a shim and the mapped executable is replaced - such is the case with pyenv) - by :user:`gaborbernat`. (#2050)

v20.3.0 (2021-01-10)

Features - 20.3.0

  • The builtin discovery takes now a --try-first-with argument and is first attempted as valid interpreters. One can use this to force discovery of a given python executable when the discovery order/mechanism raises errors - by :user:`gaborbernat`. (#2046)

Bugfixes - 20.3.0

  • On Windows python 3.7+ distributions where the exe shim is missing fallback to the old ways - by :user:`gaborbernat`. (#1986)
  • When discovering interpreters on Windows, via the PEP-514, prefer PythonCore releases over other ones. virtualenv is used via pip mostly by this distribution, so prefer it over other such as conda - by :user:`gaborbernat`. (#2046)

  • Add --read-only-app-data option to allow for creation based on an existing app data cache which is non-writable. This may be useful (for example) to produce a docker image where the app-data is pre-populated.

    ENV \
    VIRTUALENV_OVERRIDE_APP_DATA=/opt/virtualenv/cache \
    VIRTUALENV_SYMLINK_APP_DATA=1
RUN virtualenv venv && rm -rf venv
ENV VIRTUALENV_READ_ONLY_APP_DATA=1

  • Provide setup_logging flag to python API so that users can bypass logging handling if their application already performs this - by :user:`gaborbernat`. (#1896)
  • Use \n instead if \r\n as line separator for report (because Python already performs this transformation automatically upon write to the logging pipe) - by :user:`gaborbernat`. (#1905)

v20.0.24 (2020-06-22)

Features - 20.0.24

  • Ensure that the seeded packages do not get too much out of date:

    • add a CLI flag that triggers upgrade of embedded wheels under :option:`upgrade-embed-wheels`
    • periodically (once every 14 days) upgrade the embedded wheels in a background process, and use them if they have been released for more than 28 days (can be disabled via :option:`no-periodic-update`)

    More details under :ref:`wheels` - by :user:`gaborbernat`. (#1821)

  • Upgrade embed wheel content:

    • ship wheels for Python 3.9 and 3.10
    • upgrade setuptools for Python 3.5+ from 47.1.1 to 47.3.1

    by :user:`gaborbernat`. (#1841)

Bugfixes - 20.0.22

v20.0.21 (2020-05-20)

Features - 20.0.21

  • Better handling of options :option:`copies` and :option:`symlinks`. Introduce priority of where the option is set to follow the order: CLI, env var, file, hardcoded. If both set at same level prefers copy over symlink. - by :user:`gaborbernat`. (#1784)
  • Upgrade pip for Python 2.7 and 3.5+ from 20.0.2 to 20.1 - by :user:`gaborbernat`. (#1793)

Bugfixes - 20.0.12

v20.0.11 (2020-03-18)

Features - 20.0.11

  • Improve error message when the host python does not satisfy invariants needed to create virtual environments (now we print which host files are incompatible/missing and for which creators when no supported creator can be matched, however we found creators that can describe the given Python interpreter - will still print no supported creator for Jython, however print exactly what host files do not allow creation of virtual environments in case of CPython/PyPy) - by :user:`gaborbernat`. (#1716)

Bugfixes - 20.0.11

  • Support Python 3 Framework distributed via XCode in macOs Catalina and before - by :user:`gaborbernat`. (#1663)

  • Fix activate_this.py throws AttributeError on Windows when virtual environment was created via cross python mechanism - by :user:`gaborbernat`. (#1710)
  • Fix --no-pip, --no-setuptools, --no-wheel not being respected - by :user:`gaborbernat`. (#1712)
  • Allow missing .py files if a compiled .pyc version is available - by :user:`tucked`. (#1714)
  • Do not fail if the distutils/setuptools patch happens on a C-extension loader (such as zipimporter on Python 3.7 or earlier) - by :user:`gaborbernat`. (#1715)
  • Support Python 2 implementations that require the landmark files and site.py to be in platform standard library instead of the standard library path of the virtual environment (notably some RHEL ones, such as the Docker image amazonlinux:1) - by :user:`gaborbernat`. (#1719)
  • Allow the test suite to pass even when called with the system Python - to help repackaging of the tool for Linux distributions - by :user:`gaborbernat`. (#1721)

  • Fix generated scripts use host version info rather than target - by :user:`gaborbernat`. (#1600)

  • Fix circular prefix reference with single elements (accept these as if they were system executables, print a info about them referencing themselves) - by :user:`gaborbernat`. (#1632)

  • Handle the case when the application data folder is read-only:

    • the application data folder is now controllable via :option:`app-data`,
    • clear-app-data now cleans the entire application data folder, not just the app-data seeder path,
    • check if the application data path passed in does not exist or is read-only, and fallback to a temporary directory,
    • temporary directory application data is automatically cleaned up at the end of execution,
    • :option:`symlink-app-data` is always False when the application data is temporary

    by :user:`gaborbernat`. (#1640)

  • Fix PyPy 2 builtin modules are imported from standard library, rather than from builtin - by :user:`gaborbernat`. (#1652)

Improved Documentation - 20.0.3

v20.0.2 (2020-02-11)

Features - 20.0.2

Bugfixes - 20.0.2

  • Support long path names for generated virtual environment console entry points (such as pip) when using the app-data :option:`seeder` - by :user:`gaborbernat`. (#997)

  • Improve python discovery mechanism:

    • do not fail if there are executables that fail to query (e.g. for not having execute access to it) on the PATH,
    • beside the prefix folder also try with the platform dependent binary folder within that,

    by :user:`gaborbernat`. (#1545)

  • When copying (either files or trees) do not copy the permission bits, last access time, last modification time, and flags as access to these might be forbidden (for example in case of the macOs Framework Python) and these are not needed for the user to use the virtual environment - by :user:`gaborbernat`. (#1561)

  • While discovering a python executables interpreters that cannot be queried are now displayed with info level rather than warning, so now they're no longer shown by default (these can be just executables to which we don't have access or that are broken, don't warn if it's not the target Python we want) - by :user:`gaborbernat`. (#1574)

  • The app-data :option:`seeder` no longer symlinks the packages on UNIX and copies on Windows. Instead by default always copies, however now has the :option:`symlink-app-data` flag allowing users to request this less robust but faster method - by :user:`gaborbernat`. (#1575)

Improved Documentation - 20.0.2

v20.0.1 (2020-02-10)

Features - 20.0.1

Bugfixes - 20.0.1

  • Virtual environments created via relative path on Windows creates bad console executables - by :user:`gaborbernat`. (#1552)
  • Seems sometimes venvs created set their base executable to themselves; we accept these without question, so we handle virtual environments as system pythons causing issues - by :user:`gaborbernat`. (#1553)

v20.0.0. (2020-02-10)

Improved Documentation - 20.0.0.

  • Fixes typos, repeated words and inconsistent heading spacing. Rephrase parts of the development documentation and CLI documentation. Expands shorthands like env var and config to their full forms. Uses descriptions from respective documentation, for projects listed in related links - by :user:`pradyunsg`. (#1540)

v20.0.0b2 (2020-02-04)

Features - 20.0.0b2

  • Improve base executable discovery mechanism:

    • print at debug level why we refuse some candidates,
    • when no candidates match exactly, instead of hard failing fallback to the closest match where the priority of matching attributes is: python implementation, major version, minor version, architecture, patch version, release level and serial (this is to facilitate things to still work when the OS upgrade replace/upgrades the system python with a never version, than what the virtualenv host python was created with),
    • always resolve system_executable information during the interpreter discovery, and the discovered environment is the system interpreter instead of the venv/virtualenv (this happened before lazily the first time we accessed, and caused reporting that the created virtual environment is of type of the virtualenv host python version, instead of the system pythons version - these two can differ if the OS upgraded the system python underneath and the virtualenv host was created via copy),

    by :user:`gaborbernat`. (#1515)

  • Generate bash and fish activators on Windows too (as these can be available with git bash, cygwin or mysys2) - by :user:`gaborbernat`. (#1527)

  • Upgrade the bundled wheel package from 0.34.0 to 0.34.2 - by :user:`gaborbernat`. (#1531)

Bugfixes - 20.0.0b2

  • Bash activation script should have no extensions instead of .sh (this fixes the :pypi:`virtualenvwrapper` integration) - by :user:`gaborbernat`. (#1508)

  • Show less information when we run with a single verbosity (-v):

    • no longer shows accepted interpreters information (as the last proposed one is always the accepted one),
    • do not display the str_spec attribute for PythonSpec as these can be deduced from the other attributes,
    • for the app-data seeder do not show the type of lock, only the path to the app data directory,

    By :user:`gaborbernat`. (#1510)

  • Fixed cannot discover a python interpreter that has already been discovered under a different path (such is the case when we have multiple symlinks to the same interpreter) - by :user:`gaborbernat`. (#1512)

  • Support relative paths for -p - by :user:`gaborbernat`. (#1514)

  • Creating virtual environments in parallel fail with cannot acquire lock within app data - by :user:`gaborbernat`. (#1516)

  • pth files were not processed under Debian CPython2 interpreters - by :user:`gaborbernat`. (#1517)

  • Fix prompt not displayed correctly with upcoming fish 3.10 due to us not preserving $pipestatus - by :user:`krobelus`. (#1530)

  • Stable order within pyenv.cfg and add include-system-site-packages only for creators that reference a global Python - by user:gaborbernat. (#1535)

Improved Documentation - 20.0.0b2

v20.0.0b1 (2020-01-28)

  • First public release of the rewrite. Everything is brand new and just added.
  • --download defaults to False

Warning

The current virtualenv is the second iteration of implementation. From version 0.8 all the way to 16.7.9 we numbered the first iteration. Version 20.0.0b1 is a complete rewrite of the package, and as such this release history starts from there. The old changelog is still available in the legacy branch documentation.
